Video Trimmer
Cut a video down to the exact time range you need, entirely in your browser via ffmpeg.wasm.
Whether you're pulling a highlight out of a longer recording or removing dead time from the start and end, this tool cuts a video to an exact time range using FFmpeg running locally via WebAssembly. Trimming uses stream copy rather than a full re-encode, so it's fast and lossless - quality inside the selected range matches the source exactly, unlike a re-encoded export.

Common questions
What time format do I use?
MM:SS or HH:MM:SS, e.g. 1:30 for one minute thirty seconds.
Does it re-encode the video?
No - trimming uses stream copy so it's fast and lossless. If it fails on your file, the cut points may not align to a keyframe; try adjusting them slightly.
Does it upload my video?
No - trimming runs locally with WebAssembly. Nothing leaves your browser.
Can I trim and merge multiple clips afterward?
Yes - trim each clip you need here, then combine them in order with the Video Merger.
